DEVICE FOR DRESSING LOCOMCTIVE WHEELS.

Application filed December 21, 1925. Serial No. 76,940.

after more fully described and claimed, and

dressing the wheels of locomotives and has for its object the provisionof a novel device adapted to be mounted upon the brake beam or brakehanger and equipped with selectively usable cutters adapted to bebrought into engagement with the tread or flange of a locomotivewheelwhereby to dress. the same and restore the flange to normal shape and mheight with respect to the tread, after pro longed'use, so as to complywith theregulations in this respect.

It is well known that after being in serv ice for some time thetreadsand flanges of locomotivewheels become worn, the treads being grooved.to a certain extent so that the flanges project beyond the periphery ofthe treads to a greater extent than is permissible under the'law. Theordinary practice is to 2Q move the locomotive to the shop, take off thewheels, dress thewheels and return them to their proper position, anoperation requiring brought into engagement with the wheels for dressingthem without necessitating removal.

Another object of the invention is to provide aplurality of cutterswhich are removably mounted in place and which are selectively usable soas to dress the tre'ad,the flange and subsequently finish both in the 4cproper manner.

An additional object is to provide a de vice of this character whichwill be simple and inexpensive in manufacture, easy to use, positive inaction, etficient and durable in service, and a general improvement inthe art.

With the above and'other objects and advantages in view, the inventionconsists in the. details of construction and the arrange merit andcombination of parts to be herein illustrated in the accompanyingdrawings, in which 1- Figure 1 is a sideelevation of the device partlybroken away and in section.

Referring more particularly to the drawings, I have shown'the device ascomprising a body member 10 which may be conveniently constructed as acasting and which is of asize and shape corresponding at leastsubstantially to the shape of a brake shoe-of the type used onlocomotive wheels. J our flange of the wheel. The body member is formedwith an eye portion by means of which it is pivotally mounted, as shownat 16, upon a brake beam, brake hanger or the like, indicted at 1? inFigure 12. The details for moving the brake mechanism are not shown asthey are old and well known and form no part whatsoever of the presentinvention. The face of the body member 10 is formed with a transverselyarranged slot or groove 18 within which may be inserted the particulartool needed to used.

In Figure at I have shown the tool for roughing oil the tread A of thelocomotive wheel. B, this tool 19 consisting simply of a block-likepiece of high speed steel. The shape and size of the block is such thatit may be easily engaged within the groove 18 in position to engageagainst and out the tread A.

In Figure 5 I have illustrated the tool used for roughing oil theflange, this tool consisting of a block-like member 20 adapted to befitted within the notch or groove 18 and formed with a notch 21 having acontour corresponding to the proper cross sectional configuration of thelocomotive flange C. In Figure 6 I have disclosed a cutter 22 adapted tobe fitted within the groove or slot 18 for the purpose of effecting thefinishing action, this tool consisting of an elongated bar memberadapted to bear against the tread of the wheel and notched as indicatedat 23 for also bearing against the flange. In some instances there areblind wheels used on locomotives, by blind wheels it being meant thatthere are no flanges provided. In such an event use is made of thecutter 24: shown in Figure 7, this cutter being identically the same asthe cutter 22 except that it is not provided with a notch for treatingthe flange.

Referring to Figure 12, the application of the device will be readilyapparent inasmuch as the body member 10 is mounted upon the brake hanger1 7 in place of the brake shoe or near the same as illustrated, in suchposition as to engage against the wheel. When there is no cutterprovided, as shown lwa no in Figure 1, the rollers 12 will bear againstthe wheel. Whenever it is necessary to dress the wheel, the propercutter is-engaged within the groove or slot 18 of the body and the brakemechanism is set by the application of the desired amount of pressurethereto so that the cutting tool will be held against the wheel inposition to cut the band. The first step is of course to place thecutting member 19 in position to dress ofi' the ridge D which is formedon the tread of the wheel by prolonged use. After this ridge has beendressed 0d, the cutter 19 is removed and replaced by the cutter20 Shownin Figure 5 and the brake mechanism is, again set so that this cutterwill be brought into coacting relation with the flange C, as shown inFigure 9 for roughly dressing it off. Subsequently to this, the

cutter 20 is removed and replaced by the cutter 22 which will act todress the flange and also the tread as shown in Figure 10. In case thewheel is one of that type unprovided with a flange, the cutter 24: isused instead of the cutter 22, this action being illustrated in Figure11. In actual practice, after the cutting tool has been placed inposition and the proper pressure placed upon the brake mechanism, thelocomotive may be moved along a straight track by means of anotherlocomotive, crane or the like, the movement being naturally a slow one,so that the cutters employed will act to dress OK the wheels in a veryefiicient manner. In actual practice, I have discovered that the set ofwheels of a locomotive may be dressed in a very short time so that asaving in time and labor is efiected, inasmuch as it is unnecessary tolay up the locomotive by removing the wheels. It is believed that theconstruction, operation and advantages will be readily apparent to oneskilled in the art without further explanation.

While I have shown and described the preferred embodiment of theinvention, it should be understood that I reserve the right to make suchchanges in the form, construction and arrangement of parts as will notdepart from the spirit of the invention or the scope of the subjoinedclaims.

Having thus described the invention, I claim 1. In a device of thecharacter described, a body member adapted to be mounted upon the brakemechanism of a locomotive in position to be adjacent a wheel, said bodymember being provided with rollers normally engageable with the wheel,the body member being provided intermediate its ends with a transverselyarranged groove, and a cutter removably engaged within the groove andadapted to act upon the wheel for dressing the same.

2. A device for dressing the tread and flange of a locomotive wheelwhile the locomotive is travelling upon a track, comprising a bodymember adapted to be pivotally mounted upon a brake hanger, rollersjournally supported upon the ends of the body member and adapted toengage the tread of the wheel, the body member being formed centrally ofits face toward the wheel with a transverse slot, and a cutting toolremovably engaged within said slot and adapted to bear against thewheel.

3. A device for dressing the tread and flange of a locomotive wheelwhile the locomotive is travelling upon a track, comprising a bodymember adapted to be pivotally mounted upon a brake hanger, rollersjourto bear against the wheel, said cutting memnally supported upon theends of the body her being of metal and'having a contour member andadapted to engage the tread of corresponding to the propercrossvsectional 10 the Wheel, the body member being formed configurationof a normal wheel,

centrally of its face toward the Wheel With In testimony whereof I afiixmy signature.
